The effect of obliquity variations may, in concert with precession, be amplified by orbital inclination. 26. It relies on experience for analyzing equipment failure and precession limitation in actual relay protection maintenance. 27. By considering the impact of perturbation, orbital characteristics are researched mainly from three aspects including precession of orbital plane, change of orbital inclination and rotation of apogee. 28. This conclusion is consistent with the hypothesis that the rotational axis of the minor planet has no precession. 29. The tilting of the gyro continues until the erection torque balances the torque producing the precession. 30. At one time, it is proved that the expression of precession is independent of Earth model. 31.
